Syngenta Polytrin C 44 EC Insecticide (Profenofos 40% + Cypermethrin 4%)
The Ultimate Broad-Spectrum Solution for Hard-to-Kill Pests
Syngenta Polytrin C 44 EC is a powerful combination insecticide designed to fight complex pest infestations. By mixing two potent active ingredients—Profenofos and Cypermethrin—it delivers a "double punch" to pests. It works effectively against chewing caterpillars (bollworms) and sucking pests like aphids and jassids.
Best For: Farmers dealing with mixed pest attacks in Cotton, Rice, and Vegetables who need rapid results and long-lasting protection.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Knockdown Action: The Cypermethrin component stops pests from feeding immediately ("shock effect"), preventing further crop damage within minutes.
-
🛡️
Dual-Mode Protection: Combines contact and stomach action. It kills pests that touch the spray and those that eat treated leaves.
-
⏳
Ovicidal Power (Kills Eggs): Profenofos penetrates pest eggs, destroying them before they hatch. This breaks the pest lifecycle effectively.
-
🌧️
Rainfast Technology: Contains special stickers that make the spray resistant to rain wash-off once it has dried (approx. 2-4 hours).
-
🌿
Mite Suppression: Unlike ordinary pyrethroids that can cause mite outbreaks, Polytrin C actively suppresses mite populations.

How It Works: Mode of Action
Polytrin C attacks the insect nervous system at two different points, ensuring high mortality even in resistant pests.
- Synaptic Disruption: Profenofos inhibits the enzyme Acetylcholinesterase (AChE). This causes the nerves to fire uncontrollably, leading to paralysis.
- Nerve Channel Blockage: Cypermethrin keeps the sodium channels in the nerve cells open, causing repetitive nerve impulses, tremors, and rapid death.
- Translaminar Reach: The chemical penetrates the leaf surface to reach pests hiding on the underside (abaxial surface) of the leaves.
This combination creates a synergistic effect, where the two chemicals work better together than they would individually.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Bollworm Complex (American, Spotted, Pink), Jassids, Thrips, Aphids, Whiteflies |
| Rice (Paddy) | Stem Borer, Leaf Folder, Green Leaf Hopper (GLH) |
| Vegetables & Pulses | Pod Borers, Diamondback Moth (DBM), Fruit Borers, Mites |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. High water volume is essential for good coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 600 ml | 150 - 200 L | 2 - 3 ml | 14 - 21 |
| Rice | 400 - 500 ml | 150 - 200 L | 2.5 ml | 14 |
| Vegetables | 400 ml | 100 - 150 L | 2.5 - 4 ml | 7 - 14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when you see the first signs of pest damage or when the pest population crosses the Economic Threshold Level (ETL) (e.g., 5% boll damage in cotton).
- Mixing: Use clean water. Important: Do not mix with alkaline substances like Bordeaux mixture or lime, as this destroys the chemical effectiveness.
- Coverage: Ensure the spray covers both the top and bottom of the leaves, as pests often hide underneath.
- Safety: This product is highly toxic. Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use and do not re-enter the field for 48 hours.
Frequently Asked Questions
1. Does Polytrin C kill mites?
Yes. The Profenofos component is acaricidal, meaning it effectively suppresses mite populations, unlike pure pyrethroids which can cause mite flare-ups.
2. Can I use this on cucumbers or melons?
Exercise extreme caution. Cucurbits are sensitive to EC formulations and may suffer leaf burn. Always do a small test spray first.
3. Is it rainfast?
Yes, Polytrin C 44 EC is rainfast approximately 2 to 4 hours after application, once the spray has dried on the leaves.
4. What is the waiting period before harvest?
The Pre-Harvest Interval (PHI) varies: 7 days for pulses/vegetables, 14 days for rice/citrus, and up to 21 days for cotton.
5. Can I mix it with fungicides?
Yes, it is generally compatible with fungicides like Difenoconazole or Propiconazole, but never mix it with alkaline products like lime.
